Specification of Letters Patent.

Application filed December 4, 1914. Serial No. 875,415.

`new and useful improvements in Stoves, of

which the following is a specification.

My invention relates to heating stoves, and one of the `main objectsthereof is to provide such a stove wherein the air supplied to the fuelis pre-heated, thereby resulting in great fuel economy.

A. further object is to provide top, intermediate, and lower chambers,the irst of which is adapted to be placed in communication with eithersaid lower chamber or with the escape iiue of said stove, in the normaloperation of the stove or to prevent back-draft when the stove door isopened.

A further object is to provide a fire-pot of considerably less diameterthan the stove whereby an air space is provided around the same, toassist in heating the air on its way to the fuel and to increase theheat radiating surfaceof the stove; and a further ob- `ject is toprovide means for supplyinga desired amount of oxygen directly above thefire by means of what l term an over-draft.

My invention is fully described in the following specification, of whichthe accompanying drawings form a part, in which like referencecharacters are used to designate like parts in each of the views, and inwhich Figure 1 is a central, vertical, section taken through a stoveconstructed in accordance with my invention, on the line 1-1 of Fig. 3;Fig. 2 is a similar section at right angles to that shown in Fig. 1;Fig. 3 is a plan view, partly broken away; Fig. i is a section taken onthe line 4.-4 of Fig. 1; and Fig. 5 is a fragmentary front elevationthereof.

In the drawings forming a part of this application l have shown apresent preferred form of embodiment of my invention, comprising thecylindrical shell 6 having a substantially central, horizontal,partition 7 therein supporting the fire-pot 8 which has the usual grate9 at the' lower end thereof, said partition 7 being perforated atdesired points, as shown at 10, Figs. 2 and Ll. Said shell is providedwith a fuel-door 11, an airtight ash-door 12, an air supply opening 13in the top closure 14, and a flue 15 for the escape of thereof providedwith a movable the burnt gases or other products of combustion, andsaidlire-pot 8 is provided with a plurality of openings 16 therethroughadjacent the upper edge thereof, but below the partition Arrangedbeneath the opening 13 is a panshaped member17 secured to the top of thePatented Apr. 27, 1915.

stove and provided with an opening 18V on the side thereof next to theflue 15, and with openings 1,9 corresponding in number to theerforations 10 in the partition 7, and with a slot 2O for the passage ofthe arm 21 of a plate 22 slidable over the bottom of the member 17 andguided by means of a bolt 23 arranged in said member and in a slot insaid plate 22, and the outer end of said arm 21 is slotted at 211 toreceive the upper arm of a lever pivoted at 26 vand having a lower arm27. rllhe upper edge of the firedoor 11 is iianged, as shown at 28, toengage the lower end of a dog 29 pivoted at 30 and the .upper end ofwhich normally bears against the inner surface of the arm 27 of saidlever. Pivoted at 31, to the top of the stove, is a cam 32 which restsagainstthe upper lever arm 25 and is provided with a handle B3, and,when said handle is depressed, the plate 22 is lmoved outwardly, andthedog 29 is actuated to force thedoor 11 open; when said door is closed,said dog actuates the lever to move saidv plate inwardly into normalposition.

The damper plate 22 has two wings 34 provided, each, with a plurality ofperforations 35 in normal register with corresponding Openings 19beneath said wings, but, if the plate 22 is moved for a distanceequa-ling or slightly exceeding the diameter of the said` perforations,all of said openings 19 are covered by the corresponding wings, and thisforms an important feature of my invention. The plate 22 also carries,at the end Opposite the arm 21, a vertical damper 36 which normallycloses the opening 18, whereas the plate 22 normally uncovers theopenings 19, but, if the plate 22 be moved toward the front. of thestove, in the opening of the fire-door, the opening 18 is uncovered, andthe openings 19 are covered, the distance of movement of the plate 22being gaged to insure this result. Connecting each of the openings 19with a corresponding perforation 10 is a tube 37, there being four ofsuch tubes on each side of the centralline of the stove, from front toback and from side to side, in the form shown, although they may be of4any `desired number, andfin Vanyv de-A sired arrangement, but it willbenoted that no air can enter thel chamber X?" from the' chamber Xexcept through said tubes 37, theash-pit X3, the grate 9, and the fuel,not V'showrnandsthis is the only air Whichis-sulg-` plied' tothev fuel;a slight quantity of this air may, however, already described by Way ofthe openings 16 to 'supply 1 @XV-geit t'o-l saidl .that the air for; thefuelf must' come threug-lr 151 toQtl-el chimney-'n the usual manner, a)-
